Clark, are you planning to include suspensions? With suspensions , you'll find out that the tracks tension when over an obstacle. That's because teh wheels take the contours of the obstacle and the surplus of track follows the same contours, if I make myself clear. http://s148.photobucket.com/albums/s30/ChrysKane/BT-5/?action=view¤t=P 6090057.flv see and freeze seconds 4 and 3 when the brick is under the middle part of the tank, to see the difference. A relatively sagging track climbs a vertical obstacle with a very low speed. (also, in teh same video, 1 full skid per second....)
The tracks can be loose and sagging on flat terrain, when you don't need all the tension and teh vehicle rolls smoothly with less push. BUt they won't let you down when climbing an obstacle and you want the pins to engage tightly. Have fun!
